  2. Anthropometric measurement of the developing fetus - Wikipedia

    en.wikipedia.org/wiki/Anthropometric_measurement...

    Fetal height, fetal weight, head circumference (HC), crown to rump length (CR), dermatological observations like skin thickness etc. are measured individually to assess the growth and development of the organs and the fetus as a whole and can be a parameter for normal or abnormal development also including adaptation of the fetus to its newer ...

  3. Crown-rump length - Wikipedia

    en.wikipedia.org/wiki/Crown-rump_length

    An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).

    en.wikipedia.org/wiki/Prenatal_development

    An abnormally slow growth rate results in the infant being small for gestational age, while an abnormally large growth rate results in the infant being large for gestational age. A slow growth rate and preterm birth are the two factors that can cause a low birth weight. Low birth weight (below 2000 grams) can slightly increase the likelihood of ...

  6. Gestational age - Wikipedia

    en.wikipedia.org/wiki/Gestational_age

    Gestational age at birth is on average shortened by various pregnancy aspects: twin pregnancy, prelabor rupture of (fetal) membranes, pre-eclampsia, eclampsia, intrauterine growth restriction. [29] The ratio between fetal growth rate and uterine size (reflecting uterine distension) is suspected to partially determine the pregnancy length. [30]

  7. Timeline of human prenatal development - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_human_prenatal...

    Fetal heart tone (the sound of the heart beat) can be heard using doppler. Nipples and hair follicles begin to form. Location of the elbows and toes are visible. Spontaneous limb movements may be detected by ultrasound. All essential organs have at least begun. The vitelline duct normally closes.

  8. Pregnancy Outcome Prediction study - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_Outcome...

    Third-trimester screening of nulliparous women by universal ultrasound fetal biometry increases the detection rate of large for gestational age (LGA) infants and, combined with ultrasound measurements of fetal growth velocity, identifies those at increased risk of adverse neonatal outcome. [13]

  9. Human embryonic development - Wikipedia

    en.wikipedia.org/wiki/Human_embryonic_development

    The normal period of gestation (pregnancy) is about nine months or 40 weeks. The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus. The germinal stage takes around 10 days. [1] During this stage, the zygote divides in a process called cleavage.
